What is the standard deviation and what is the probability that a student scored higher than 322 if the mean test score is 312 and 16 percent of the scores are under 307?

Description : What is the standard deviation and what is the probability that a student scored higher than 322 if the mean test score is 312 and 16 percent of the scores are under 307?

Last Answer : Assuming a normal distribution:If 16% are less than 307, then 84% are greater than 307.Using single tailed normal tables we want the z value whichgives 84%-50% = 34% = 0.34 to the left of the mean; this is z ≈ ... 1 - 0.977 = 0.023 = 2.3 % are greater than 322→ probability greater than 322 is 2.3%
